The Missing Door

There are two situations that trip up new users when it comes to doors. I wrote about about one of these Reviteristics in April 2010. That post is about Openings and this one is about curtain wall panel doors.

When people first make a curtain wall that is supposed to get a door they quite naturally assume the door tool is the right place to start. Wrong. Curtain walls are special and they are made up of curtain grids, panels and mullions. A curtain wall door is really a curtain wall panel. They are a panel because Revit needs to keep their width and height flexible, to accommodate any changes we might make. A regular door family can vary in size but it can't respond to curtain grids being moved. We can't even put a regular door in a curtain wall. That's not entirely true but I'd have to get into yet another Reviteristic, using other wall types as curtain wall panels.

We need to understand that a door in a curtain wall isn't a "door", at least not to the Door tool. To make matters a bit more confusing Revit treats this curtain wall panel, pretending to be a door, as a door in schedules and in Visibility/Graphics.

    It would be better if we could click on the Door tool and have the option to place a "regular" door or a "curtain panel" door. At least this way it would become immediately apparent that there is a difference!

Curtain wall panel doors are found in the Doors folder within the content library. That seems slightly logical, in the same way that Opening families are found there. When we want to load a curtain wall door family, browse to the door library (stock content location).

Placing a curtain wall door is a bit different than a regular door in a wall. We don't use the Door tool. We have to swap out the panel that should be a door with the curtain wall door family that you loaded. To do this we need to use the TAB key to select the panel and then use the Type Selector to choose the curtain wall door family instead.

Once you do this you'll have to make sure that the curtain grids and mullions are adjusted to report the desired size. If you set the grids and mullions before the door is in place you'll find that the size is not quite the clean numbers you probably wanted. You can resolve this with mullions that use different offset values or just re-position the curtain grids until you get a cleaner door size.

I captured another video in the "Five Minutes with..." theme.



If you want to create a new curtain wall door family you ought to examine and/or reverse engineer the stock one first. You can start from scratch with the family template (Door - Curtain Wall.rft)

Using Edit Profile on a Curtain Wall

I recently responded to a post at RevitForum.org when a member asked about creating what sounded to me like a round top window using a curtain wall. I posted a couple screen captures and briefly discussed how they were made. This first one is a curtain wall embedded in a host wall followed by using Edit Profile to alter the sketch of the curtain.


This one is a bit more involved. I started with a single rectangular curtain wall and copied it to clipboard. Then I used Edit Profile to change it's shape. I then used Paste Aligned > Same Place to put the original curtain wall back on top of the first one. Using Edit Profile again allowed me to follow the edge of the first and design the second wall. Repeat the steps for the third and we have a curving set of mullions that are defined by three curtain walls that have complimentary sketches defined using Edit Profile.


I mentioned the use of the parameter Automatically Embed, a feature of curtain wall. The curtain wall types that are present in the stock templates vary but the simplest ones like Curtain Wall1 don't have the feature selected. If you sketch one of these walls over the top of another you'll get an error message.


I posted the following image because I thought it was worthwhile mentioning that the Cut Geometry tool the warning message references allows us do things like this too.


I also created a video that discusses these concepts.
